Mainly distributed in China, Mexico and the United States. Because Lenovo is headquartered in China, China has naturally become the main production location for Lenovo's all-in-one computers. At the same time, Lenovo has also built factories around the world, such as in Mexico and the United States, where it also produces Lenovo all-in-one computers. In addition, Lenovo will also adjust the origin according to market demand to meet the needs of users in different regions.

Its products include notebook computers, desktop computers, all-in-one computers and other types. In recent years, Lenovo's all-in-one computers have performed well in the global market and become one of the most popular products among consumers.

Generally speaking, the power of Lenovo all-in-one computers is about 80-300 watts. This is because the size and configuration of Lenovo's all-in-one computers will have an impact on power. Generally speaking, Lenovo all-in-one computers with high configuration and large screen have higher power, while Lenovo all-in-one computers with low configuration and small screen have lower power. In addition, the power of different models of Lenovo all-in-one computers will also be different. Although the power of Lenovo all-in-one computers usually does not exceed 300 watts, if the power is used improperly, it may cause problems such as overload or short circuit. Therefore, when using Lenovo all-in-one computers, we should pay attention to its power and not let it exceed the rated power to avoid safety problems.

There may be several reasons that cause the laptop screen to display blur.
1 An incompatible or wrong graphics card driver is installed, or the driver is wrong or missing or the driver file is incomplete, etc. It can cause the graphics card to display blur, black screen, or even crash. If this is a driver problem, you can uninstall the original driver and reinstall the correct driver.
2 Graphics card overclocking causes graphics card screen distortion. There are some third-party overclocking software that can improve the game performance of the graphics card by modifying the graphics card data and unlocking relevant settings. However, this kind of overclocking can cause instability of the graphics card, especially long-term use, which will increase the probability of graphics card problems. In this case, the solution is to turn off overclocking. And restore the graphics card to its default values.
3 Laptop screen distortion may also be caused by the laptop screen. The laptop monitor is connected to the computer motherboard through a flat cable. If the connected flat cable is loose, has poor contact, or the flat cable is contaminated by foreign objects, it will cause abnormalities in the display screen. In this case, you can try to pat and press it first to see if there is any change. Of course, you should not use too much force. It is possible for miracles to happen if you use force. If you have the ability, just take it apart and look at the cables. If you don’t have the relevant experience, just spend money to go to a computer repair shop for repairs.
4The last point may be the inherent fault of the machine. Some manufacturers' products are notorious for causing problems. We can’t call the brand by name, after all, it is now a major manufacturer. In the past, I cut corners, used poor capacitors, and used second-rate, third-rate or unknown video memory. Everything that can be shrunk can be shrunk. If you are unlucky and encounter this situation, there is nothing you can do. You get what you pay for. Stay away from such machines.
